Is it possible to wire up an shower extractor fan (timed with light) so that it comes on only when the isolation switch (Dual Pole) for the shower is on?
e.g. switch shower on from pullcord switch, extractor comes on with shower. Switch shower off at pullcord isolator, extractor overruns for set period of time.
I can only see us using the extractor for when we use the shower, so we wouldn't really need it to come on everytime we switch the light on when we enter the bathroom.
I'm assuming we would still need a seperate isolation switch (3 pole) for the extractor anyway?
Cheers
